SPECIFICATION forming part of Letters Patent No. 745,026, dated November 24, 1903.

Application filed March 5, 1903.

To 60% whom it may concern.-

Be it known that I, EPPA H. RYON, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts,have invented certain new and usefullmprovementsinTake-Up Mechanism, of which the following is a specification.

My invention relates to a take-up mechanism particularly adapted to be applied to and used on looms for weaving heavy fabrics, such as cotton-duck; and the object of my invention is to provide an improved take-up mechanism or mechanism for rotating the take-up or cloth roll at a gradually-reduced speed as the fabric accumulates on the roll.

My invention consists in certain novel features of construction of my take-up mechanism, as will be hereinafter fully described.

I have only shown in the drawings detached portions of a loom-frame with my improved take-up mechanism combined therewith, sufficient to illustrate the nature of my improvements.

Referring to the drawings, Figure 1 is a side view of my improvements with a portion broken away for the sake of clearness. Fig. 2 is an end View and partial section of the parts shown at the right in Fig. 1 looking in the direction of arrow at, same figure. Fig. 3 is, on an enlarged scale, an inner perspective View of the internal ratchet-wheel and gearing and the central pivoted lever and gears detached; and Fig. 4 shows the internal gear-wheel 3O detached and a weight mechanism instead of a spring mechanism combined therewith.

In the accompanying drawings, 1 is a portion of the loom side or frame. 2 is the bottom or driven shaft of the loom, on which is fast a double cam 3. A roll 4 (shown by dotted lines in Fig. 1) on the rocking arm 5, pivoted at its lower end on a stud 5, engages the periphery of said cam 3 and is held in engagementtherewithbyaspringii. Supported on the rocking arm 5 is a collar 7, adjustable up or down thereon and adapted to be secured thereto.

To the collar 7 is pivotally secured one end of a connector 8. The other end of said connector is pivotally connected to one arm, 9, of

, loose on the stud 10.

.ver 18, in this instance by pins 19.

Serial No. M6270. (No model.)

an angle-lever 9, loosely mounted on a stud 10, secured to the loom-frame at its inner end and having a bearing 10 at its outer end in the bracket or stand 11, bolted to the loom on a pin 12 is pivoted a pawl 13, (see Fig. 1,)

adapted to engage theratchet-teeth on the 1 internal ratchet-wheel 14, the hub 14: of which (see Fig. 2) is fast on the extended hub 15 of the pinion 15, loose on the stud 10. Fig. 2.)

The pinion 15 is intermediate and meshes with the pinions 16 and 17, mounted on the studs 16 and 17, fast in the oppositely-extended ends of the centrally-pivoted lever 18, (See Fig. 3.) A pinion 19, loose on the stud 10, is secured to the le- (See Fig. 2.) The pinion 19 meshes with the intermediate pinion 20, loose on a stud 21 on the loomframe,(see Fig. 1,) and through pinion 22, keyed on the shaft 23, mounted in hearings on the loom-frame, rotates the shaft 23 and the pinion-24, keyed thereon, which meshes with the gear 25 and rotates said gear 25, fast on the shaft 25 of the take-up roll 25". (See Fig. 2.)

The arm 9 of the angle-lever 9 has pivoted to its outer end the lower end of an adjustable connector 26, (see Fig. 1,) and the upper end of said connector is pivotally connected with the slotted end of an arm 27, loosely mounted on a stud 28. Also mounted on said stud 28 is the hub 29 of the segment-gear 29. Said hub has a shoulder adapted to engage a corresponding shoulder or projection on the hub 27 of the arm 27, (see Fig. 2,) the construction being such that the arm 27 may be freely moved in an upward direction by the angle-lever 9 and the extent of its downward motion be controlled by contact of the said shoulders on the hubs 27 and 29, respectively." It will be understood, of course, that many variations maybe made in this specific feature of structure without departing from the spirit of my invention. The segment- (See gear 29 meshes with the gear-teeth 30', formed on a portion of the periphery of the internal gear-wheel 30, (see Fig. 3,) the hub 30 of which is connected the lower end of a tensionspring 36. The upper end of said spring 36 is attached to an adjustable hook 37, secured to a plate 38, bolted to the loom side. The spring 36 acts to retard the revolution of the gear-wheel 30.

In place of the lever 34 and spring 36 I may use a weighted arm 41, fast on a rockshaft 42, and a cam-arm 43, also fast on said shaft 42 and connected by a chain 44 with the book 31 on the internal gear-wheel 30, as shown in- Fig. 4. The weighted arm 41, through cam-arm 43 and chain 44, acts to retard therevolution of the gear-wheel 30, the same as the spring 36.

The spring 36 or weighted arm 41 and connected parts act as a yielding controller upon the gear-wheel 30, so asto maintain a substantially uniform tension and winding of the cloth as the roll increases in size.

A holdfast-pawl 39 is pivoted on a pin 40, supported in the stand 11, and is weighted at one end, 39. The other or engaging end engages the internal ratchet-teeth on the ratchetwheel 14.

The operation of my take-up mechanism is as follows: The revolution of the cam 3 with the shaft 2 through the roll 4 rocks the arm 5 and through connector 8 rocks the angle lever 9 on the stud 10, and the pawl 13, moving with the angle-lever 9 and engaging the teeth on the ratchet-wheel 14, rotates said ratchet-wheel fast on the hub 15 of the pinion 15 and also rotates said pinion in the direction of arrow b, Fig. 1, and through the pinions 16 and 17, meshing with the pinion 15, rotates the lever 18 and the pinion 19, andthrough intermediate pinions 20 and 22, shaft 23, pinion 24, gear 25, and shaft 25 rotates the take-up roll 25 to wind the fabric. As the rotation of the take-up roll 25" causes more of the fabric to be wound thereon, said fabric travels on a constantly increasing arc of a circle and the take-up roll 25 imparts a gradually-increasing resistance to the operatingears, which in their turn transfer said resistance to the centrally-pivoted lever 18, having the gears 15 and 16 thereon. This resistance due toincreasing size of clothroll will cause the internal gear-wheel 30 to revolve against the tension of spring 36 or weighted arm 41, and the teeth 30 thereon, meshing with the teeth on the gear-segment 29, will rock'said gear-segment on the stud 28, and the shoulder on the hub 29 of said gearsegment will engage the shoulder on the hub 27 of the arm 27 and will act as a stop to hold said arm 27 and prevent thelink 26 from dropping down as much, and consequently the pawl 13 will engage less teeth on the ratchetwheel 14 to rotate said ratchet-wheel. As the internal gear-wheel 30 rotates more, due to the increasing resistance of the take-up roll, the connector 26 will be raised higher and cause the pawl 13 to engage less teeth on the ratchet-wheel14, with the result that the takeup roll 25', will travel a shorter distance each time. chain 33, connected to the book 31, acts as a tension for retarding the revolution of the internal gear-wheel 30. The weighted pawl 39 acts as a holdfast-pawl to hold the ratchetwheel 14 after it has been partially rotated by the pawl 13.

It will be understood that the details of construction of my improvements may be varied, if desired.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In a take -up mechanism for looms, a cloth-roll, a stud or shaft, a regulating-gear loose on said stud or shaft, and means for retarding its rotary motion, a rotating arm carrying a pinion fast near its fulcrum, a stud near the free end of said rotary arm and carrying aloose pinion, the said loose pinion adapted to engage both the regulating-gear and driving-gear, and said driving-gear, and operative connections between the drivinggear and clothroll, substantially as shown and described.
